We demonstrate a robust lithographic patterning method to fabricate self-supported sub-50 nm VO(2) membranes that undergo a phase transition. Utilizing such self-supported membranes, we directly observed a shift in the metal-insulator transition temperature arising from stress relaxation and consistent opening of the hysteresis. Electric double layer transistors were then fabricated ...

Iron-overload cardiomyopathy is a major cause of death in thalassemic patients. However, pathways of non-transferrin-bound iron (NTBI) uptake into cardiomyocytes under iron-overload conditions are still controversial. We previously demonstrated that Fe(2+) uptake in thalassemic cardiomyocytes is mainly mediated by T-type calcium channels (TTCCs). However, direct evidence regarding Fe(3+) uptake, the ...

Accumulating evidence indicates that inflammation plays a critical role in cancer development. Cyclooxygenase-2 (COX-2) is a rate-limiting enzyme for prostanoid biosynthesis, including prostaglandin E(2) (PGE(2)), and plays a key role in both inflammation and cancer. It has been demonstrated that inhibition of COX-2 and PGE(2) receptor signaling results in the ...

A wide range of molecules, from inorganic to biological, self-assemble on surfaces. Previous studies have elucidated many features of solute reorganization on surfaces using coarse-grained modeling, implicit solvent, and constraints such as chemically bonding the solute to the surface. Using molecular dynamics simulations under various combinations of interaction parameters, solute ...

We report the piezotronic effects on the photoluminescence (PL) properties of bent ZnO nanowires (NWs). We find that the piezoelectric field largely modifies the spatial distribution of the photo-excited carriers in a bent ZnO NW. This effect, together with strain-induced changes in the energy band structure due to the piezoresistive ...

The integrity of the blood-brain barrier (BBB) is critical to normal brain function. Traditional techniques for the assessment of BBB disruption rely heavily on the spatiotemporal analysis of extravasating contrast agents. However, such methods based on the leakage of relatively large molecules are not suitable for the detection of subtle ...
